ATTACHMENT FOR PICKS.

Specification of Letters Patent.

Patented Nov. es, 191 o.

Application filed January 18, 1916. Serial No. 72,820.

To all whom it may concern Be it known that I, LENIA GREENWOOD, a

citizen of the United States, residing at Q asonville, in the county of Greene. and State of Indiana, have invented new and useful Improvements in Attachments for Picks, of which the following is a specification.

This invention relates to attachments for picks and more particularly to those types of picks used in the mining of coal where, in the use of the picks, that portion of the handle adjacent the pick blade is subjected to a large amount of wear or chipping due to its contact with the sharp corners of the coal.

A primary object of my invention is to provide a simple device composed of two identical members so constructed as to have locking engagement with each other and to completely coverthat portion of the handle that is subjected to wear.

An object of the invention is to construct a device of the character specified in which the parts are so related with relation to the handle and pick blade that the device will be prevented from moving in any direction, and such result is obtained in a very inexpensive manner without operating upon the pick blade or weakening the pick handle.

A further object of the invention is to provide a device composed of two members of identical construction and of such shape as to be readily stamped from sheet iron or other metal, thus reducing the expense of manufacturing the device.

lVith these and other objects in view the invention consists in the construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the claims hereunto appended.

In the drawing: Figure 1 is a side elevation of a pick showing my invention about to be applied thereto. Fig. 2 is a view of a pick showing my invention applied but the tongues arranged out of their final position. Fig. 3 is a side elevation of a pick showing my invention completely assembled upon the pick handle. Fig. 4 is a perspective view of one of the members. r

In the drawing, the numeral 1 designates a pick handle enlarged at its point of juncture with the pick blade 2, the latter being of well-known ponstruction but illustrated in the drawing as that type of blade used in the mining of coal.

The attachment comprises two identical members 3 and 4:, and as the two members are of similar construction, I will limit my description to one. The member 3 is stamped or formed in any other suitable manner to conform to the curvatureof the pick handle and to snugly engage the undersurface of the pick blade 2, and due to this construction and arrangement the member is prevented from moving in a direction toward the pick blade 2, thus counteracting the greatest portion of strain to which the attachment is subjected in the use of the pick. The longitudinal edge 5 is slotted at spaced intervals to form a series of tongues 6, and adjacent the remaining longitudinal edge the member is provided with a number of slots 7, equal in number to the tongues.

In assembling the device upon the handle the members are brought into tight engagement with the pick handle with the tongues of one member inserted in the slots of the other member. As soon as this position is reached the tongues are bent back upon the associated member in order to accomplish an interlocking engagement between the members. Thus it will be seen that the members are held against independent movement away from each other while the pick blade prevents movement of the device in one direction. To prevent movement of the attachment in the remanding direction, that is toward the hands of the operator, I insert a number of securing elements 8 through the tongues and into the pick handle.

From the foregoing description, it will be seen that in a very simple manner without weakening the handle or drilling'uponthe pick blade I am enabled to attach a device that will effectually prevent wear and chipping of the handle when contacting with foreign bodies.

From the foregoing description taken in connection with the accompanying drawing it is to be apparent that I have provided a device which is admirably adapted for the purpose for which it is intended, that the device is simple, durable and efiicient of construction, and that the device may be manufactured and sold at a comparatively low cost.

Change in the form, proportions and minor details of construction may be made tongues of one member being inserted in the slots of the other member When the members are arranged around the pick handle, and securing elements passed through the tongues When in the assembled position and into the pick handle.

2. An attachment for picks comprising a pair of members completely inelosing that portion of the pick handle adjacent the pick blade and each member provlded with a series of tongues adapted to pass through and bend over slots formed in the other member, said parts being bent in a direction to lock said members together, and securing elements passing through said members and engaging the plck handle and cooperating with said tongues to prevent movement of the members in any direction.

In testimony whereof I ailix my signature in presence of twowitnesses.
